Koremods

Koremods is a Kotlin Script bytecode manipulation framework. It providers modders a new way of transforming (not just) minecraft bytecode with rich IDE support and Gradle integration.

This Modrinth project contains releases for Koremods Modlauncher, the MinecraftForge frontend.

Main Features

  • 📦 Sandboxed
    • Koremods scripts are executed in an isolated environment to ensure they only access necessary classes and resources
  • ⚡ Focused
    • Using the ASM Kotlin wrapper Koffee, you can focus on writing transformers without needless boilerplate code
  • ☁ Lightweight Runtime
    • Near-instant evaluation speeds of scripts pre-compiled by the Koremods Gradle plugin
  • 🧩 Portable
    • Koremods' feature-rich core allows easy compatibility with your desired platform
    • Frontends only need to create a thin layer beween the platform and Koremods Script.
  • 🖋️ Rich IDE Support
    • Koremods offers first-class syntax highlighting and autocompletion thanks to IntelliJ IDEA’s Kotlin Script support

Documentation

Kotlin Script

Kotlin Scripting is a new, experimental technology that lets you run Kotlin code without prior compilation or packaging. All of Kotlin's language features are available, usually with the addition of a speficic DSL provided by the script definition. Scripts are compiled into bytecode at runtime, and then loaded into the JVM using a custom classloader.
